Searched numerous, threads but did not find any help on how to trim the gasket for the front main seal. Do u trim flush with the pan?? I did force it in the grouve with a piece of round stock. have about 3/16" overhang each end.
 
I don't trim it at all. Just leave it the way it comes out and pull the pan down. If you take the pan off 6 months from the install date doing it this way you will find the ends fit fine.
 
I went by an article by Frank Rosin, The Restorer - Mar/Apr 2002 article that I found somewhere. Title: Leakless Pan Gasket. Haven't run engine yet so who knows?

I've had to trim most of the rope seals I use. I use a sharp razor blade and just keep moving back and forth like a saw. First I form the seal to the pan by using a large socket, then leave enough seal to allow for the thickness of the gasket plus about 1/8" to 3/16". Grease the seal well befor installing the pan.

If you look into some of the part supplier catalogues , they advise...DO NOT trim this seal stock.

I have done exactly as Tom has described and have not seemed to have any issues, however, james has done more than all of us and I'm sure it will squish down. There's probably a point of the perfect amount of mass to seal it vs/too much. Seems like the new ropes squish a little more than they use to.

My experience is it will depend on which gasket kit you have
I install mine with a dolly to compress them into the grove as much as possible so finish proud the correct amount 1/8-3/16 but some need a slight trim
 
As we can see here by the responses from respected Model A guys; trim, no trim, and in other past threads, soak, no soak, it makes no real difference in the end result.

We know it makes no difference because we have had our successes using either method
 
Thanks to everyone who responded. And there very usefull tips. I installed the pan this morning. Used a piece of round stock the correct size and a hammer to seat the rope in the pan, did not trim. Its was proud about 3/16" on both sides. grease it up real good, went right on real smooth. used 4 pilot bolts in the corners to drawn the pan tight, removed and replaced after all others were tight. My first work on and "A"!!

I am a new "A" owner, and decided to drop the pan and clean the sludge, not as much as i was expecting. Then checked and adjusted rod and main clearance. Should be ready to run this afternoon!!! THANKS AGAIN TO ALL THAT RESPONDED!! Tim
